Propane & LPG Tank API

Propane and LPG tank maths as an API, computed locally and deterministically — the usable-fill, energy and burn-time numbers a homeowner, RV-er, grill-master or HVAC tech works out at the tank. The tank endpoint turns a tank size into real numbers: liquid propane is 4.24 lb per gallon and holds 91,452 BTU per gallon (about 21,569 BTU per pound), so a 20 lb barbecue cylinder carries roughly 4.7 gallons and 431,000 BTU. It knows the two ways tanks are sized — a portable cylinder (20, 30, 40 lb) is rated by the propane weight it holds, while a bulk tank (100, 250, 500, 1000 gal) is filled to only 80 % of its water capacity to leave room for expansion, so a 500-gallon tank actually holds 400 gallons of propane and about 36.6 million BTU. The burntime endpoint divides that energy by an appliance’s BTU-per-hour input rating to give run time: that same 20 lb cylinder runs a 30,000 BTU/hr patio heater about 14 hours, and an optional hours-per-day turns it into days. The refill endpoint costs a fill from a price per gallon, gives the cost per 100,000 BTU so you can compare propane to natural gas or electricity, and — with an appliance rating — the running cost per hour. Everything is computed locally and deterministically, so it is instant and private. Ideal for home-energy, HVAC, RV, off-grid, grilling and outdoor-living app developers, fuel-cost and tank-monitor tools, and propane-delivery calculators. Pure local computation — no key, no third-party service, instant. US units. Live, nothing stored. 3 compute endpoints. For vehicle fuel economy or the ideal gas law use a different API.

Front-Month Futures Quotes API
Live continuous front-month (1!) quotes for the major liquid futures across every asset class, with no key: precious & base metals (gold, silver, copper, platinum), energy (WTI crude, natural gas, gasoline, heating oil), grains (wheat, corn, soybeans), softs (coffee, sugar, cocoa, cotton), livestock, equity-index (E-mini S&P 500, Nasdaq, Dow, Russell), interest-rate (2/5/10/30-year Treasuries) and FX futures from COMEX, NYMEX, CBOT, CME, CME_MINI and ICE US. Get a per-contract quote by short code (GC, CL, ES, ZW) with last price, % change and intraday OHLC, a full cross-asset board, or a per-category cut — a curated board of the contracts that actually trade.

Commodity Movers & Performance API
What is moving across the commodity complex right now, computed live from Yahoo Finance futures (no key, nothing stored). Just as stock, FX and crypto traders watch the day's biggest gainers and losers, commodity traders want the same board for energy, metals, grains, softs and livestock. For every commodity this measures the change on the day, the week and the month, the day's high and low, the 52-week high and low and where the price sits in that 52-week range. The movers endpoint returns the whole complex ranked by daily change — the top gainers and losers — plus the weekly and monthly leaders, and can be filtered to one sector. The commodity endpoint returns one commodity's full performance card. The commodities endpoint lists what is covered. The commodity movers / performance-board cut — distinct from the commodity-momentum API (which ranks by a blended multi-month momentum factor and trend regime), the commodity-price feed, the commodity-spreads and the seasonality APIs. It answers what moved today, across the complex.

Commodity Seasonality API
The calendar patterns commodity traders position around, computed live from ~10 years of Yahoo Finance monthly futures data (no key, nothing stored). Commodities are the most seasonal market there is: natural gas tends to rally into winter heating demand, gasoline into the summer driving season, grains around the planting and harvest calendar. This measures it directly — for each commodity it takes a decade of monthly returns, groups them by calendar month, and returns the average return in each of the twelve months, the share of years that month was positive (the win rate), and the historically strongest and weakest months. The seasonality endpoint returns one commodity's full 12-month seasonal profile plus the current month's historical bias. The month endpoint flips it around: for a given calendar month it ranks every commodity by its historical average return, so you can see what is seasonally bullish or bearish right now. The commodities endpoint lists what is covered. The commodity-seasonality / calendar-pattern cut — distinct from the FX-seasonality API (currencies), the commodity-price feed, the commodity-spreads and the commodity-momentum APIs. It answers what a commodity usually does this month, not what it costs today.

Commodities Momentum & Relative-Strength API
Which corner of the commodity complex is leading and which is lagging, ranked by trailing momentum, computed live from Yahoo Finance futures (no key, nothing stored). A price tells you where a commodity is; momentum tells you where the money is flowing. This scores every major commodity — crude, Brent, natural gas, gasoline and heating oil in energy; gold, silver, copper, platinum and palladium in metals; corn, wheat and soybeans in grains; coffee, sugar, cocoa, cotton and orange juice in softs; live cattle and lean hogs in livestock — by its return over five horizons (1 week, 1 month, 3 months, 6 months and a ~1-year proxy), blends them into a single momentum score and ranks the whole complex into leaders and laggards. The screener endpoint returns that ranked table with a relative-strength rank and trend regime for each. The momentum endpoint drills into one commodity: its multi-horizon returns, where it sits versus its 50- and 200-day averages, and a trend label. The commodities endpoint lists what is covered. The cross-commodity momentum / relative-strength factor cut — distinct from the commodity-price feed (front-month prices), the commodity-spreads API (crack/crush/ratios) and the precious-metals spot API. It answers what is leading the complex, not what one thing costs.
